[QUOTE="audioholic, post: 600612, member: 549629"] Most of the SQL drivers you guys are talking about, the W7, XXX and Brahma, are BL optimized drivers. Read up on XBL^2 and JL's method of BL optimizing the dub, you'll find the design was intended purely for SQ purposes, and long excursion capabilities were merely a bonus side effect of the overall design. Ive seen representatives from the manufacturers of all three of these subs say that. Even looking back to the old days of one of the first long excursion drivers, the GZ Nuke, its design intent was SQ. I think if you want to nitpick further than that, you are just being arguementative.
